NUMERICAL STUDY OF FLOW AND HEAT TRANSFER OF CASSON FLUID OVER AN EXPONENTIALLY POROUS STRETCHING SURFACE IN PRESENCE OF THERMAL RADIATION

The present paper aims to study the of flow and heat transfer of anon Newtonian Casson fluid that passes an exponentially porous stretching surface in the presence of thermal radiation. Using similarity transformations the governing partial differential equations are converted into ordinary differential equations and solved using an implicit finite difference scheme known as a Keller Box method. It is observed that increasing values of Casson-parameter decreases the velocity and increases the temperature field. Radiation parameter increases the thermal diffusivity and temperature. Skin friction increases with an increase in suction.
